In the fifth-generation communication systems [1]}, [2]},
Network slicing (NS) aims at replacing the traditional one-size-fits-all
network architecture. NS may address diverging requirements imposed
by verticals [3]} while reducing operational
costs [4]}, [5]}, thanks to its ability to provide
higher network flexibility. NS exploits network virtualization to
elastically allocate and reallocate infrastructure resources tailored
to the time-varying needs of various applications [6]}, [7]}.
With NS, multiple slices, i.e., customized,
isolated, and service-dedicated end-to-end logical
networks, can be established and operated simultaneously on a shared
physical infrastructure network, provided by one or several Infrastructure
Providers (InPs) [8]}.
